Hi, "- Your user submits a form to an action that takes a long time, but gets impatient, presses STOP, and submits the form again. You now have two simultaneous requests to deal with."
But is there any specific set of methods to deal with the Multiple requests simultaneously from a user ? 1 . If the second request needs to be killed and only the First request should be processed 2 . All the simultaneous requests should get processed .. Thanks.

Most browsers will fire off simultaneous requests for each frame, which shows up at the server as multiple requests on the same session. - Your application uses <img src="..."> tags to dispay images, and those images are in the same webapp. Again, the browser will fire off multiple requests simultaneously. - Your user submits a form to an action that takes a long time, but gets impatient, presses STOP, and submits the form again. You now have two simultaneous requests to deal with. Craig -- To unsubscribe, e-mail: <mailto:[EMAIL PROTECTED]> For additional commands, e-mail: <mailto:[EMAIL PROTECTED]>
